"I want to foresee the failure of the rotating machine." 'Wiserot'

Before abnormalities occur! Early detection of abnormal signs in rotating machinery! Prevent failures in advance and achieve a reduction in maintenance costs.

"Wiserot Wireless" is a monitoring system for rotating machinery that contributes to preventive maintenance by early detection of abnormal signs in rotating machines. By using our unique judgment criteria (Q value), it enables early detection of bearing abnormalities, thereby reducing downtime. Additionally, we offer the "Wiserot LAN type (wired)," which, while equipped with similar functions to the wireless version, eliminates the need for battery replacement by adopting an AC adapter. 【Features of Wiserot Wireless】 ■ Detection of abnormal signs through trend monitoring of high-frequency vibrations ■ Reduction of maintenance costs through alleviation of maintenance tasks and safety measures ■ Cutting inverter carrier vibration noise using our proprietary diagnostic technology ■ Easy installation on existing equipment due to the wireless sensor equipped with a battery ■ Measurement possible even in areas where wiring is difficult ■ Trend monitoring of various vibration values (acceleration, velocity, displacement) is possible *For more details, please refer to the PDF document or feel free to contact us.

Power Supply BCP Measures: Seismic Device for Transformers 'TTR Type'

Seismic measures start with "transformers"! We achieve efficient disaster reduction measures (damage mitigation and early recovery).

The seismic isolation device "TTR type" significantly reduces the displacement of transformer terminal sections caused by large seismic motions, preventing large-scale power outages due to transformer damage. With the installation of TTR, a displacement of ±50mm or less at the terminal section has been achieved for all experimental seismic waves. Based on the building's response characteristics, it is possible to calculate and simulate the displacement of the transformer during an earthquake. In past earthquakes (such as those in Eastern Japan and Kumamoto), the heaviest transformers in the cubicles were damaged, resulting in many cases where emergency generators could not supply electricity even if they were intact. Transformers are not readily available, meaning that operations would be halted during that time. TTR not only protects the transformer but also enhances the overall rigidity of the cubicle, contributing to the protection of various relays and LCBs. TTR realizes efficient disaster mitigation measures. 【Features】 ■ Special absorbers at the top of the transformer significantly suppress displacement caused by seismic motions. ■ Effective even against continuous earthquakes. ■ Can be installed within the cubicle. ■ Minimal changes to panel size with TTR installation. ■ Does not compromise the effectiveness of the installed vibration isolation device. *For more details, please refer to the PDF document or feel free to contact us.

"Transformer Seismic Resistance: Even if the emergency power generation is safe, the transformer is important." TTR

Seismic measures start with "transformers"! We achieve efficient disaster reduction measures (damage mitigation and early recovery).

With the installation of the TTR, a displacement of ±50mm or less at the terminal sections has been achieved for all experimental seismic waves. It is possible to calculate and simulate the displacement of transformers during earthquakes based on the building's response characteristics. In past earthquakes (such as those in Eastern Japan and Kumamoto), the heaviest transformers in substations were damaged, leading to many cases where electricity could not be extracted even if emergency generators were intact. Transformers are not readily available, meaning that operations would be halted during that time. The TTR not only protects the transformer but also enhances the overall rigidity of the substation, contributing to the protection of various relays and LCBs.
